1962 Revox E36 & F36
Back to gallerySpecifications


Tape recording technology continued to advance rapidly throughout the early 1960's and the E36 (left, top) was engineered to provide the mixing facilities, echo and multiple recording possibilities that enthusiasts were seeking.

The E series was the first Revox to be introduced to the British market in any quantity, appearing early in 1962.

The single magic eye indicator on the E36 could, with the help of a switch, show level for channel 1, channel 2 or the sum of both.

Since Continental standards differed from those in the UK, a revised edition of the E36 (the F36) was provided to satisfy the requirements of international use as far as possible.

With the F36 (below, left) more features were included, making the machine easily the most versatile available. In addition to employing the latest recording characteristic, the F-36 was also the first (and only) Revox to use the graduated twin beam magic eye with its incredibly short rise time, giving an accurate register of transients. To my knowledge, Tandberg was the only other manufacturer to use this type of level indicator.


This 'snappy' double magic eye which, incidentally, I'm told is a very rare EMM801 type valve, could simultaneously show both channels at the same time.

Both machines were available in half track or quarter track stereo versions and could take 10 inch reels.

The E36 was the first Revox to use semiconductors (in the pre-amp only, it was a hybrid unit with valves in the output stages). The F36 reverted back to an all-valve design..
